Hi Michael =)
I was thinking of writing something about optimising the execution of the algs for Pyraminx but I ran into a notation problem. Take this example:
U B U B' U
When I do that alg I do not do that, it is a 2-gen and of course I use R-L, U-B is just because all cases in my description are from the same angle, again because it is a poorly developed notation used for Px, there are no pussle orientations. What I do when executing that alg is
R2' -- orient around R axis -- L R L' R -- orient back R' (it's great, insert it in L -alg- L' and it does U-PLL)
Got any ideas of how to solve this problem? Invent a notation?
It does make a big difference, If I do R x R x' R I have to change grip at R-side at some point but if I do R2' x R x' R I do not have to change it. It is a good idea to write about it because of that.
Writing this to you because I know you'r good at speedsolving px and also because you, like me, write to the Px articles =)

- About Pyraminx: I don't really know about fingertricks because I've never had a puzzle that would consistently let me do them. I always just use wristing for pyraminx... I think I do understand what you're talking about though. Perhaps we could invent some kind of separate notation for algorithms where l would be turning the face opposite the R corner, and similarly r, d, f. It would conflict with the notation for the tips, but nobody ever talks about turning tips during an algorithm and we won't need these moves during a scramble, so it should be fine. Of course we can also use x (orient around R), y (orient around U), z' (orient around B), and maybe, I dunno, w? (orient around L)... I haven't really been writing about the algorithms themselves, but it's cool that you're interested in writing them down the way they would be fingertricked. Maybe eventually we could have diagrams of the case too, like the PLL page. qqwref 18:52, 1 September 2008 (UTC)
- Doing it the wiki way, your reply under my first post -- of course, then it is much easier to follow the tread. Because it was me who wrote first at your page I will watch it for replies. Also, you wrote at my page, not my talk page :P
- Yeha, you did not know, next time you get it right :)
I was thinking of the lower case thing for faces (r = L-face, r' = L' and so on), it is useful and maybe 3R, 3U, 3L and 3B for orientations (three layers)... I work something out. Kenneth 04:17, 2 September 2008 (UTC)
- EDIT: here is my try Pyraminx notation#Extensions to the notation:. Does it look good? =)

- Yeah, that looks good. Writing turns like (R) is a good choice but it might interfere with normal parenthesis notations, so how about (r) or cR? qqwref 22:58, 3 September 2008 (UTC)
- Yes, or maybe <R> I think I change to that. "cR", hehe c = "cube", it is a tetra, tR would be OK =) // Kenneth 04:13, 4 September 2008 (UTC)
- I like <R>. But tR looks weird :P Oh well. qqwref 04:05, 6 September 2008 (UTC)
Category:Images. Click it =)
If you put that category to the image pages they will all automaticly become listed as thumbnails. I made a few templates that are useful, (you can see them in the first section of that page) one for PD images, one for GNU licence and one for copyrighted images (used under permission). The image category is included in these templates so if you use them the images will also be listed automaticly at the image category.
If you like the images to be in some more specific category, then just create it =) // Kenneth 09:44, 22 November 2008 (UTC)
x and other x
- Well, wikipedia's not exactly a major cubing resource :p The x's are way more useful if you ask me, because that way you can quickly search through the page to find e.g. the 7x7x7 UWRs. If the page gets bigger that will be pretty much a necessity. qqwref (talk) 23:01, 27 January 2015 (UTC)
